Qt: CUDA with Qt OSX Yosemite "sed: illegal option - r" error

I am creating a simple app with Qt creator in which I want to use CPU and GPU calculations to complete a task and then compare the execution times in m / s.

I read a lot of articles and came to the conclusion that I need to separate the NVCC and GCC compilers from each other to avoid conflict. I followed this tutorial while making settings for my system, however, when I compile, I get a strange error:

sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]
make: *** [gaussian_cuda.o] Error 1
14:42:46: The process "/usr/bin/make" exited with code 2.

      

        
        
        
      

    

Obviously the error is being inferred from this line in my config .pro

:

2>&1 | sed -r \"s/\\(([0-9]+)\\)/:\\1/g\" 1>&2

      

        
        
        
      

    

I don't understand why this is an illegal operation and when I try to delete this line my code breaks completely.

Why r

is it illegal?
